Bypass image captcha and reCAPTCHA with bestcaptchasolver service, JS library
npm install bestcaptchasolver-client
or
git clone https://github.com/bestcaptchasolver/bestcaptchasolver-javascript
Promises are used inside the library, for better code management
Simply require the module, set the auth details and start using the captcha service:
<!-- Load jQuery (dependency) -->
<script src="http://code.jquery.com/jquery-3.3.1.min.js"></script>
<!-- Load the API library -->
<script src="../lib/bestcaptchasolver.js"></script>Set access token, before using the library
bestcaptchasolverapi.set_access_token('access token from /account');Get balance
bestcaptchasolverapi.account_balance().then(function (balance) {
console.log('Balance: $', balance);
})Submit image captcha
The submission of image captcha is done by sending us the image as a b64 encoded string.
bestcaptchasolverapi.submit_captcha({
b64image: captcha,
// is_case: true, // case sensitive, default: false, optional
// is_phrase: true, // contains at least one space, default: false, optional
// is_math: true, // math calculation captcha, default: false, optional
// alphanumeric: 2, // 1 (digits only) or 2 (letters only), default: all characters
// minlength: 2, // minimum length of captcha text, default: any
// maxlength: 3, // maximum length of captcha text, default: any
// affiliate_id: 'ID of affiliate' // default: None, optional
}).then(function (id)) { /* use id to retrieve text */ };Submit reCAPTCHA
The page_url and site_key are the only requirements. There are other optional parameters though.
bestcaptchasolverapi.submit_recaptcha({
page_url: 'PAGE_URL_HERE',
site_key: 'SITE_KEY_HERE',
// other parameters
// -------------------------------------------
// reCAPTCHA type(s) - optional, defaults to 1
// -------------------------------------------
// 1 - v2
// 2 - invisible
// 3 - v3
// 4 - enterprise v2
// 5 - enterprise v3
//
// type: '1',
//
// user_agent: 'Your user agent',
// proxy: 'abc:[email protected]:4321 or 12.35.56.78:4321',
// v3_action: '', // v3 action
// v3_min_score: '0.3', // if v3, score to target
// domain: 'www.google.com', // optional
// data_s: 'recaptcha data-s parameter used in loading reCAPTCHA',
// cookie_input: 'a=b;c=d', // used in reCAPTCHA solving, optional
// affiliate_id: 'ID of affiliate' // optional
}).then(function (id)) { /* use id to retrieve response */ };Just like the image submission method, this method also returns an ID, which is then used to get the text or gresponse.

bestcaptchasolverapi.submit_task({

// user_agent: 'your UA',
// proxy: '12.34.54.56:1234'
// affiliate_id: 'ID of affiliate'
}).then(function (id)) { /* use id to retrieve solution */ };Update task variables while it is being solved by the worker. Useful when dealing with data / variables, of which value you don't know, only after a certain step or action of the task. For example, in websites that require 2 factor authentication code.
When the task (while running on workers machine) is getting to an action defined in the template, that requires a variable, but variable was not set with the task submission, it will wait until the variable is updated through push.
The bestcaptchasolver.task_push_variables(captcha_id, push_variables) method can be used as many times as it is needed.
bestcaptchasolverapi.task_push_variables(captcha_id, {"tfa_code": "49651"})Retrieve
Retrieval is done by passing the ID, for all captchas
bestcaptchasolverapi.retrieve_captcha(id).then(function (data) { console.log(JSON.stringify(data)); });This method returns an object, with the text attribute for image captcha or gresponse if submission was done for reCAPTCHA
or solution for geetest and capy
If reCAPTCHA is submitted with proxy, get proxy status
log('Recaptcha response: ' + data.gresponse);
log('Proxy status: ' + data.proxy_status);Set captcha bad
bestcaptchasolverapi.set_captcha_bad(captcha_id);Check the examples folder
